GvG fights are becoming more common as guilds set out to test their metal against their counterparts in WvW the only problem is there is no facilitated areas that guilds can do this that doesn’t disrupt either WvW itself or spectators jumping in and screwing things up.
A system implementing a large arena where cross server and same server guilds can set up matches against each other and spectators can join the viewing areas and then placed as non combatants would be nice.
